用线性规划方法建立农业生产最优结构和合理布局模式刍议

本文着重说明运用数学方法对农业生产结构与布局进行定量分析的必要性与可能性.通过分析农作物播面指数、单产指数和播面结构指数三种因素在农业产量增加中所起的作用,说明调整农业生产结构的重要意义;同时采用线性规划方法确定农业生产最优结构和合理布局模型.通过三类约束方程的建立.具体分析了建模过程以及选取参数和建立约束方程时应注意的一些问题.

RESEARCH FOR THE ESTABLISHMENT OF THE OPTIMAL AGRICULTURE STRUCTURE AND THE RATIONAL AGRICULTURE DISTRIBUTION MODELS BY LINEAR PROGRAMMING

This paper consists of three parts. First, the necessity and possibility of qnantitative analysis in agriculture by mathematical methods are stated; the functionar relations between agriculture development and the input of factors, and the influence of adjustment of agriculture structure are analysed. Second, it's stated that lineal programming is one of the efficient methods to describe the production and distribution structure in agriculture. The process of the establishment of the model, some problems with the selection of parameters and constrain functions are analysed in detail. Finally, it's necessary to make the utilization programme of land when the agriculture structure model is set up, so that an optimal model further utilization of land is analysed.
